Blood samples from 2,500 injured drivers were analysed for alcohol, cannabinoids (measured by the presence of THC), benzodiazepines and stimulants. The relationship between the prevalence and concentration of drugs and the culpability of the driver was examined using an objective method for assessing culpability. There were no significant differences between males and females with respect to cu...

background and aim: injuries from traffic accidents are a major public health problem, and the third leading cause of mortality in people aged 1 to 40 years. each year 31.8 persons per hundred thousands of iranians are killed in car accidents. neighboring of north khorasan province with razavi khorasan, a province with a lot of pilgrims caused a large number of passengers travel via north khora...

BACKGROUND Back injuries are common in transit drivers, and can result in substantial direct and indirect cost to the employer and employee. Whole-body vibration (WBV) is one risk factor for drivers. Standards have been adopted (ISO 2631-1) to guide researchers in measuring and analysing WBV levels. Lately, a new standard has been added (ISO 2631-5) that takes impulsive exposures into account. ...

Recent developments in the car industry have put Human Machine Interfaces under the spotlight. Developing gratifying human-car interactions has become one of the more prominent areas that car manufacturers want to invest in. However, concepts like emotional design remain foreign to the industry. In this study 12 experts on the field of automobile HMI design were interviewed in order to investig...

The aim of this study was evaluation of interior design of Shoka vehicle with respect to the accommodation for Iranian population and proposing suggestions for customizing design of the vehicle. Methods: This study was a descriptive-analytical study conducted a...

The aim of this study is to find association between some groups of occupational stressors and serum lipids and glucose concentrations in professional drivers in road traffic. The study included 417 male professional drivers (162 inter city bus drivers, 36 suburban bus drivers, 33 city bus drivers, 81 truck drivers, 71 official car drivers and 34 professional taxi drivers). Occupational stresso...

Accident studies emphasise the high frequency of perceptual errors made by car drivers when colliding with motorcycles (in 60 or 70% of these accidents, according to Van Elslande & Jaffard, 2010, and Hurt et al., 1981, respectively). The errors are identified as non (or late) detections of the motorcycle on the one hand (e.g., Cavallo & Pinto, 2012), and as a misperceptions of the motorcycle's ...

A general class of car-following models is analyzed where the longitudinal acceleration of a vehicle is determined by a nonlinear function of the distance to the vehicle in front, their velocity difference, and the vehicle’s own velocity. The driver’s response to these stimuli includes the driver reaction time that appears as a time delay in governing differential equations. The linear stabilit...
